PCD
(Polycrystalline Diamond) has been available for milling
non-ferrous abrasive materials for many years. The common
method of tool production has been grinding using Diamond
grinding wheels. The
forces required to grind PCD with Diamond are extremely high. This means that it has been very difficult to produce cutting
tool inserts accurately enough to work properly in the fixed
pocket milling cutters commonly available. Cutters with adjustable
pockets for the inserts were developed, but these require
care and patience to set up and are expensive to buy
and repair. Using
the latest Wire erosion technology David Richards have developed
techniques which produce PCD tipped cutting tool inserts that
are as accurate as Precision ground carbide. Installed
in the best quality Diamite cutter bodies, Diamite PCD inserts
provide all the Tool life and quality advantages of PCD with the convenience of Carbide.
